>ALTER SERVER</TT

   server.  The first form changes the server version string or the
   generic options of the server (at least one clause is required).
   The second form changes the owner of the server.
  </P
><P
>   To alter the server you must be the owner of the server.
   Additionally to alter the owner, you must own the server and also
   be a direct or indirect member of the new owning role, and you must
   have <TT
CLASS="LITERAL"
>USAGE</TT
> privilege on the server's foreign-data
   wrapper.  (Note that superusers satisfy all these criteria
   automatically.)
